Overpopulation is an undesirable condition where the number of the existing human population exceeds the actual carrying capacity of Earth. Is global overpopulation caused by a number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are a few of the causes which result in overpopulation. It is possible for a sparsely populated area to become densely populated if it is not able to sustain life.
Some of the major effects of human overpopulation are:
Loss of freshwater
Due to overpopulation and our constant need for factory-made products, there has occurred a loss of freshwater in the rivers and oceans. Factories discharge all their waste material in the rivers and lakes which results in loss of freshwater. Pollution in water bodies is not only limited to the source of factory waste. Domestic sources due to overpopulation also play a significant part in contributing to the pollution and loss of freshwater in water bodies.
Global warming and climate change
Another negative impact that overpopulation has had on the environment is clearly visible in the form of global warming and climate change. Scientists all across the world are worried about the changing global weather cycle and constant rise in the average world temperature.
Extinction of species
Climate change, global warming, and overpopulation have terrifying effects on other species. Terrifying to the levels of the whole species being extinct from the face of the earth. The previous five extinctions in the span of 450 million years have occurred due to natural causes like volcano eruptions or meteorites. Scientists are afraid that the sixth extinction would be caused by climate change and global warming.
Overpopulation is a problem that did not arise overnight and its solution cannot come up in a single day. Controlling overpopulation is a long term process and requires a lot of planning. The government of one’s country has a huge role in checking overpopulation.
